Q:LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?

SMD patch products basically can be used in reflow soldering, especially a little note here that the eutectic welding is the connection between the chip and the substrate support or specifically, is the bottom of the chip after completion of production of coating material and a layer of Sikkim alloy, and then set up a heating zone in solid crystal machine package in time and a temperature of about 300 degrees, the realization process of the chip at the bottom of the Sikkim alloy melt and silver plated layer connection bracket, and a clear distinction between reflow.

Q:Which is good for LED patch and LED bulb?

LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;

Q:SMD LED specification

The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.

Q:How to install the patch LED lamp band?

Installed indoors, you can directly tear off the stickers on the 3M double-sided adhesive surface, and then fix the light bar where it needs to be installed. Just press it with your hands.

Q:Patch LED features

Without heating time, lighting is faster than general light (about 3 ~ 400ns).The electro optic conversion efficiency is high, the power consumption is small, and the energy consumption is about 1/3 ~ 1/20 than that of the bulb.

Q:Patch LED manual welding, how can welding not burn lights?

When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.

Q:What does "1210" mean in patch LED?

1210 refers to the lamp specifications.LED common lamp specifications and parameters of patch0603, 0805, 1210, 3528, 5050 refers to the LED lamp belt, often used in light-emitting components ----LED size (English / Metric) name, for example, 0603 refers to the length of 0.06 inches, width of 0.03 inches. But note that the 3528 and 5050 units are metric

Q:Is the forward voltage drop of the patch LED too large or too small?

Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you

Q:What is the rated current for the white patch LED?

The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.

Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?

LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only
